Got this back from that email I sent Digiflavor:
I heard very good things about the SIREN GTA. However I heard you are not producing anymore. I wanted to order one before it is too late, however I have heard that you will be releasing and updated version. I wanted to know if this was actually the case. If so, is there a timeline that this product might be ready? Also, many reviews state that they wish that there was one more airflow setting (smaller) pehaps .50-.60% smaller that the current smallest setting. They say they simply twist it a bit more for that desired effect. Maybe you could consider that as one of the improvements to what seems to be a already great product. Any information would be great. Thank you!
"hi vern, siren v2 has been finsed on design and will be released no later than next month. please watch it and i believe it wont let you down. thanks."
We'll see what happens. In the meantime I ordered the current version and will go from there!
